September 2026 CPI Shows Rising U.S. Inflation Amid Iran War
The consumer price index (CPI) in the United States rose by 3.7% year-over-year in September 2026, up from 3.4% in August, according to data released by the Bureau of Labor Statistics. The increase is largely attributed to higher energy prices driven by the ongoing Iran war and rising oil costs. Core CPI, which excludes volatile food and energy components, also climbed to 2.6%, signaling persistent inflationary pressures beyond temporary factors. Economists warn that these trends may prompt the Federal Reserve to consider further interest rate hikes in its effort to control inflation, especially as Treasury bond yields have already risen sharply this year, increasing borrowing costs for consumers and businesses alike. The timing of the report is significant ahead of midterm elections where affordability remains a key concern among voters. The war has also contributed to declining consumer sentiment, with barometers like the University of Michigan’s index hitting multiyear lows in September 2026.
